Emergency services were called to the school on Macquarie Street, Parramatta, at 4.45am, where they found a building on the grounds well-alight.

The blaze was extinguished by firefighters and was significantly damaged with the estimated costs to repair the building being more than $10 million.

Luckily, the building was not in use and no-one was injured at the time of the blaze.
